• Before measuring voltages, always make sure that the meter is not set to a measuring
range for current.
• The voltage between the connection points of the meter and the earth potential must
not exceed 1,000 V DC/AC in CAT IV III or 600 V in CAT IV.
• The measuring prods have to be removed from the measured object every time the
measuring range is changed.
• Be especially careful when dealing with voltages higher than 25 V alternating (AC) or
35 V direct voltage (DC)! Even at these voltages it is possible to receive a fatal electric
shock if you touch electrical conductors.
• Check the meter and its measuring lines for damage before each measurement.
• Never carry out any measurements if the protecting insulation is defective (torn, ripped
off etc.).
• To avoid electric shock, make sure not to touch the connections/measuring points to be
measured directly or indirectly during measurement.
• During measuring, do not grip beyond the grip range markings (which you can feel)
present on the test prods.
• Do not use the multimeter just before, during or just after a thunderstorm (lightning!/
high-energy overvoltage!). Make sure that your hands, shoes, clothing, the oor,
circuits and circuit components are dry.
• Avoid operating the product near:
- strong magnetic or electromagnetic elds
- transmitter aerials or HF generators.
This could affect the measurement.
• Do not switch the meter on immediately after it was taken from a cold to a warm
environment. The condensation that forms might destroy your device.
• Allow the device to reach room temperature before switching it on.
• Also observe the safety information in each chapter of these instructions.
